Maybe I'm calling the wheels the wrong name. Technically the rims are F104W Tamiya Front rims for rubber tires from the 1979 Lotus F1. Since the front end is F103, I figured they are f103 front rims but don't know this for sure. They are NOT F103 Foam rims. No listing on the Tamiya site for replacement tires for this car (that I can find). I don't have any problem just getting a new set of rims for the tires available. I'll probably have to scour e-bay for a set of original tires for the original rims and use them for display only. I'll also try Tamiya customer service. They amazingly provided a replacement set of tires for a Ferrari 312B 1/12 plastic kit I built in 1975!

Anyone have any tips on fitting F104 front suspension to a F103? It seems pretty straightforward.

Thanks in advance!

Well off the top of my head, I would use an F104 chassis as a template and bolt the two chassis together at the front. I’d use the two large screws that hold the F103 beam front end to the chassis. This seems to be the common area between the two cars. The drill out any additional holes that you would need, like the servo mounting holes and the two rear holes of the F104 front end.

After writing the above, I took a look at the two cars I have here at work. From eyeballing the screw patterns, it looks like the 104 front end will mount directly to it. Keep in mind I haven’t actually measured them, but it looks pretty straight forward. I’m not sure what else you would need to look for.

If somebody else would like to share some insight, please do.

You can use a f103 front end on a F104 so why wouldn't it work the other way around?
Maybe you have to drill a hole or 2 but nothing serious.

The front ends are interchangeable as Tamiya use exactly the same chassis mounting holes. There are quite a few parts needed though, the only parts you can use from the F103 are the steering arms and springs. Here is the F104 Pro manual http://www.tamiya.com/japan/download...al/f104pro.pdf and you can work out what's needed from it. You will need to get the D parts as you need the F104 servo mounts from it as they are part of the suspension mounts.

How does this car compare to a F104 with the F104 front suspension fitted? Down here in New Zealand the F103 is still one of the best cars to have and to be honest, there has been no reason for me to buy a later model car. We use 200mm + foams are allowed. I believe the F103 has the correct dimensions and battery placement to be hard to beat on an outdoor tracks.

I was wondering the same thing.
Why make a skinny 103?

Now a wide 104 series car or even 101W, I'm guessing will be hard to beat where the 200mm car is legal.

I hope these 200mm cars come back in style here soon, says the proud owner of a new TRF 101W.

I made mine because we no longer run 200mm/foams at national level, and considering I have plenty of spare F103 cars it was cheaper to fit an F104 front end on it to go narrow instead of buying a whole car for a handful of races.

It took a bit of tuning to get the balance right but once sorted it goes just like you would expect a short wheelbase pan car, changes direction nicely but isn't as stable as a normal wheelbase modern chassis.
